| Yes, deep async I/O has practical applications -- here's an example (which is now outdated, but sans io_uring, demonstrates the issues with "async I/O" on most Unicies sans Solaris) - https://speakerdeck.com/trent/pyparallel-how-we-removed-the-... > Every OS will have to when it runs out of resources.

Or are you claiming that io_uring integrates async IO throughout the OS whereas epoll didn't?
